Commissioning and HOTO

ABC specialises in Green Star Commissioning and Hand Over-Take Over (HOTO) of commercial buildings and data centres. Commissioning (Green Star, retro or otherwise) is the process of setting to operation all equipment associated with the provision of air conditioning and services to a building in accordance with design standards; and gauged against their actual performance. This includes pumps, air conditioning units, coils, water flow rates etc.

Engineering services systems for data centres require tight coordination between the trades, special consideration for redundancy and reliability, and carefully scripted commissioning of systems.

Compared to office facilities, the risk of failure in data centres is compounded by several issues:

  1. With high density loads the time for recovery from equipment or system failure is much shorter.
  2. The cost of failure is much higher; and
  3. As loads may cluster within any groups of racks, redundancy must be provided in the "downstream" distribution system as well as the central plant.

Contractors' project teams understand the critical inter-relationships between engineering services systems and the building structure, architecture and fit out.

"Hand Over–Take Over" or HOTO means the commissioning process is interwoven with the overall project delivery process including planning, design, construction and post-construction stages.

The process is equally as important for office buildings as data centres. Long term savings add value.
